thanks for all your effort.
this is still my favorite concept, but is lacking some of the crispness and power of the other designs. maybe it's the lighting/shading effects on the font - i'm not sure.
i wish i could describe it better, but there is a harsh light effect cutting across the top half of all the letters. so instead of adding robustness and impact to the fullest extent it could, the lighting seems to distract from the message.
i have had a couple people comment that it comes off as "cartoony".
sorry if that doesn't make any sense. i hope you can think of a creative way to address it, because the other color treatments didn't seem to be better.
